Substitute Part Grouping Explanation

Substitution eligibility for the T41-3-1.00A-01-31 is determined by strict equivalence across the following critical parameters: breaker type (magnetic hydraulic delay), current rating (15A), AC voltage rating (250V), DC voltage rating (65V), actuator type (toggle), pole configuration (2-pole), and mounting method (panel mount). All substitute parts must maintain identical electrical performance characteristics and physical mounting compatibility. The identified substitutes—T21-61-25.0A-01-10AL and T21-62-15.0A-01-31AL—meet these requirements while differing only in base product number designation, reflecting alternative design variants within the SNAPAK® series that deliver equivalent functional performance.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—T41-3-1.00A-01-31, T21-61-25.0A-01-10AL, and T21-62-15.0A-01-31AL—are active production items manufactured by Sensata-Airpax with RoHS compliance certification and MSL Level 1 rating. Selection among these equivalents may be based on inventory availability, procurement lead time, or design documentation requirements. The T21-61-25.0A-01-10AL offers the highest current inventory level at 762 units, while the T21-62-15.0A-01-31AL maintains 663 units. All parts carry identical electrical ratings, mechanical mounting specifications, and regulatory compliance status, ensuring functional interchangeability within applications designed for the T41-3-1.00A-01-31.

Frequently Asked Questions (FAQ)

Q: What makes T21-61-25.0A-01-10AL and T21-62-15.0A-01-31AL equivalent to T41-3-1.00A-01-31?

A: These parts are parametric equivalents because they share identical electrical specifications (15A, 250V AC, 65V DC), breaker technology (magnetic hydraulic delay), actuator configuration (toggle), pole count (2-pole), mounting method (panel mount), and regulatory compliance (RoHS). Differences in base product numbers reflect design variants within the SNAPAK® series that deliver equivalent performance.

Q: Can these substitute parts be used interchangeably in existing designs?

A: Yes, within the scope of the electrical and mechanical parameters specified. All three parts maintain identical current ratings, voltage ratings, pole configuration, and panel mount compatibility. Physical dimensions and mounting hole patterns must be verified against application-specific requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical RoHS compliance status, MSL Level 1 rating, ECCN classification (EAR99), and HTSUS code (8536.20.0020).

Q: What is the significance of the different base product numbers (T41-3, T21-61, T21-62)?

A: Base product numbers indicate design variants within the SNAPAK® series. Despite these designations, the complete part numbers specify identical electrical and mechanical parameters, making them functionally equivalent for applications requiring 15A, 250V AC / 65V DC magnetic hydraulic delay protection.

Q: How should inventory availability influence part selection?

A: Inventory levels are provided for procurement planning purposes. T21-61-25.0A-01-10AL currently has the highest stock level (762 units), followed by T21-62-15.0A-01-31AL (663 units) and T41-3-1.00A-01-31 (697 units). Selection may prioritize availability based on project timeline requirements.
